3. Mainly used in middle school physics teaching, to explore the relationship between buoyancy and the object\'s boiled water.
4. Can stimulate children\'s interest, practical ability, exploration spirits, imagination, analytical ability, etc.
5. Complete tools, you can operate it yourself, suitable for enthusiasts.
Specification:
Item Type: Archimedes Principle Overflow Cup
Material: Plastic + ABS
Instructions:
1.Verify Archimedes\' Law:
2. Put the plastic cylinder in the plastic bucket, and the two are close to the volume of the plastic bucket, that is, the volume of the plastic cylinder.
3. Hanging the plastic bucket (with plastic cylinder inside) on the hook of the left dynamometer to read its weight.
4. Take the plastic cylinder out of the plastic bucket and hanging it on the hook under the plastic bucket, you can see that the pointer shows the same number. The reading at this time is .
5. Then the cylinder is immersed in the overflow liquid filled with water, the dynamometer display value gradually decreases, and it can be seen that the object immersed in the liquid is subjected to buoyancy, and the buoyancy can from the difference between the two indications of the pointer. When the cylinder is immersed, the buoyancy is the greatest.
6. After the overflow cup is immersed in the plastic cylinder, pour the overflowing liquid (dispose of a cup in the nozzle) into the plastic bucket. It can be seen that the pointer returns to the initial reading, which proves that the buoyancy of the plastic cylinder is equal to the amount it expelled. The weight of the liquid.
It is concluded that the object immersed in the liquid is subjected to upward buoyancy, and the buoyancy is equal to the weight of the liquid discharged by the object. This is Archimedes\' Law.
Use a dynamometer to weigh out any object to be measured. Calculate its mass, then immerse it in the overflow cup, weigh the liquid discharged from the overflow cup with a dynamometer to calculate the volume V, which is the volume of the measured object (any irregular shape is acceptable). From the following, the density of an object of any geometric shape to be measured can be obtained.
That Is: P=m/v
According to the above principles, the determination of the density of different liquid objects in the load line of a ship can be demonstrated.
Maintenance and Precautions:
1. Hanging the dynamometer vertically when in use, and adjust it through the upper thread so that the indicator points to the \"0\" scale line.
2. Put the dynamometer flat in the box after use, and don\'t be squeezed by heavy objects.
3. Wipe clean the plastic cylinder and overflow cup of the plastic bucket after use.
